The inner face of this spacing ringreceives-a bearing (air-the outer face-0f the "inner shell 1. p

,In this mannerthe shells -1 and 6 are main tained spaced apart andmounted for relative I rotative adjustment; Th'e extent of} such ad:jus'tment is-limitedby astoppi'n 9 carried {by jjthe shell 1, 01 -.the;bearing;c0llar 5zthereon, I and projecting outwardtherefromintoaslot 10cut in the left-hand end of the outer shell 6. The end walls 11 of thisslot constitute stops which coact with the stop pin 9 to limit therelative rotative adjustment between the shells 1 and 6 in oppositedirect-ions.

In order to normally lock the two shells to turn together I haveprovided a hand releasable locking device or detent which in the presentinstance comprises a spring arm 12 fastened at its'inner end at 13totheinnershell 1 and extending at its free end portion through an opening 14in the closed end of said shell and the platent head 2. The outer end ofthis spring constitutes a finger piece by which it may be moved towardsthe axis .of the platen against its spring force to release the detent.

A locking'pin 15 is fixed to the spring 12 and projects out from a sidethereof. This pin fits and is adapted to en-Z gage in any one of aseries of equallyspaced locking openings 16 extending around in theinner face of the spacing ring .7, and when in position therein locksthe two shells to turn together in any position of theirlrelativeadjustment. When the latch or detent is released such relativeadjustment may be effected.

The outer platen shell 6 has an unobstructed opening or slot 17' thatextends therethrough longitudinally of the platenand substantiallythroughout the length thereof. This slot opens into the space or channel18 provided between the two shells land 6 by maintaining them spacedapart by the m-embers 5 and 7. A card, such for example as 19 or 20sh0wnin Figs. 7 and 8 respectively, may be introduced into the slot 17 andhave a portion of it received in the channel 18 in either directionaround the platen.

When using the platen with cards of the type indicated, it is intendedordinarily that I the portion of each card which is cut or slotted, asat 21, and at which'the interlocking ears or tabs 2 are provided, shallbe received within the platen and covered and protected by the-outershell 6, leaving the uncut portion of the card exposed on the outersurface of the platen, where ordinarily indications are written thereonabove the line 28. Now in order to aid in quickly effecting this resultand in holding a card in the exact po-' sition to which it should beadjusted on the platen with the proper depth of card contained withinthe platen, I have provided end stops and card clamping devicescontained wholly within the platen and arranged be-' 'yond the walls ofthe opening 17 which will now be described.

A sheet,stri p or plate 24 of spring metal is secured at 25 intermediateits'free edges 26 to the inner platen shell 1 and extends longitudinallythroughout a considerable portion of the length thereof. The plate 2 isflexed outward so that the free edge portions 26 thereof arepressed-against the inner face of in one direction through said opening,wherethe other end stop coacts with an edge of acardintroduced throughsaid opening in the opposite direction.

In order to insure a card being properly arrested against either endstop, depending on the direction it is inserted through the opening 17and to insure that the card will "be held orclamped in place whenagainst an end stop, I have provided the following means within theplaten.

A series of spring strips 28-extend around the inner shelllbetweenthemember 2d and said shell. .Each strip 28 is attached intermed1ate itsends by any suitable means, at 29, to the member 24 and springs outwardat itsfree end. The free end portion of each strip 28 has an inclinedportion 80 that ClOsSGS" the'channel 18 and providesa deflecting facethat directs the advancing edge of an incoming card towards the outershell and into cooperative relation with the associated end stop 27. Thebase of each deflecting member? 30 is bent to provide a contact orclamping portion31 between which and the adjacent free edge portion 26of the member 24 a cart is forced as it is being directed to abuttingengagement with the associated end stop 27.

Thisresults in clamping the card in its adjusted positlonand 1n holdlngit clamped to the platenin'such pos1t1on as the printing on'the cardproceeds, enabling, nevertheless, printed card to be quickly withdrawnand re placed bya new card when desired.

It will be seen that the cards 19 and 20 are of dilferent depths andthat it is necessary to insert the-card19 to a greater depth in theplaten than the card-20 in order that the ears" 22 on the firstmentioned card may be received within the platen'and be protected frominjury. For this reason the relation between the opening 17 in the outershell of the platen,

and the endstops 27 (as'well as the spring clamping members '31)attached to the inner shell. is-made variable, such variation beingbrought about by the relative rotative adjustment between the two platenshells 1 and. 6

'hereinbefore described.

Ordinarily the index cards are inscribed on the top edge portions ashereinbefore pointed out, and as indicated at 32 in Fig. 7

In this event the lower' end st0p 27 and clamps 31, as the parts areshown in Fig. 5, would come into use and be adjusted for cards of theparticular depth "in use. In such circumstances only this set of clampsand the associated end stop are required and in such instances the useof the second end stop and asagainst which an edge of a card receivedsary to, write an inscription near the bottom sociated clamps might bedispensed with. However, it sometimes occurs that it is necesedges ofthe cards as'well as'at the top edges;

sary to employothe second or uppermost'end stop 27 (as the parts areshown in Fig. and associated clamping fingers. Therefore, I prefer toemploy both sets of saidparts' at opposite sidesofthe opening 17 as theycontribute to a wider range of use and meet the varying-requirements. orObviously the construction of the present invention maybe employedinconnection with cards which differ materially from those shown andth-emanner desoribed-ofusing the construction maybe varied.

- Various changes may be made, and parts of the construction maylee-employed without others, without departing from my invention it isdefined in the accompanying claims. What I claimas new and desire tosecure r by Letters Patentis:
